Question

Producer gas is a mixture of:
A.$CO$ and ${H_2}$
B.$CO$ and ${N_2}$
C.$S{O_2}$ and ${H_2}$
D.None of the above

Answer 1

Producer gas is a combustible mixture of nitrogen, carbon monoxide and hydrogen generated by passing air with steam over burning coke or coal in a furnace.

Complete step by step answer:
Produces gas is generally a fuel gas that is manufactured from coke. It can be produced by partial combustion of various fuels. It has lower heating value than other gaseous fuels. It is used as a fuel in industries. It is cheap to make, that's wh6y large amounts are made and then burnt.
Producer gas has many uses and advantages some of the uses and advantages of producer gas are:
It is used in furnaces to do scrubbing. In gas engines, it is used after scrubbing.
It can be more easily transmitted than solid fuel.
It avoids the smoke nuisance.
With this gas, an oxidising and reducing flame can be obtained.
Gas-field furnaces will be maintained at constant temperature.
There will be no loss due to smoke and convection current.
Producer gas can be produced even by the poorest quality of fuel.
Therefore, producer gas is a mixture of carbon monoxide, hydrogen and nitrogen. That is, it is a mixture of $CO + {H_2} + {N_2}$.
Hence, both options A and B are correct.

Note:
In the USA, producer gas refers to wood gas, town gas, synthesis gas, syngas or raw gas. Producer gas is very cheap to make.The key difference between water gas and producer gas is that the water gas contains flammable gases whereas the producer gas contains both flammable and non-flammable gases. Both water gas and producer gas are mixtures of several gases. Water gas contains carbon monoxide and hydrogen gases.
